Is the prayer of a girl who stimulated her sensitive organ, and from whom a transparent, viscous fluid, not resembling semen, was discharged, then she performed istinja and prayed without ghusl, valid, or must she perform ghusl?

It appears that what came out from the girl was madhy (pre-ejaculatory fluid). The difference between a woman's maniy (seminal fluid) and her madhy has been explained in previous fatwas. What the girl did is correct and sufficient, and she is not required to perform ghusl (definition) (ritual bath) unless the emission of maniy is confirmed. As for one who doubts whether what came out from her is maniy or something else, she may choose and assign it the ruling of whatever she wishes from that which she doubted.
